errrrrrrr, I don't have any recommendations of works written in Japanese. Sorry.
The Alan Watts writings and videos on Zen Buddhism is usually a first stop.
Other than that, I'd say hit buddhanet.net and dharmaweb.org and start blundering.
Robert Ornstein is another source (see this section of Big Sur audio tapes
http://www.bigsurtapes.com/merchant.mv740.htm).
I'll also recommend just about anything from the Dalai Llama -- yeah, he's Tibetan Buddhist but he also communicates the most straight forward practical applications of Buddhist principles in daily life. I think he's more accessible because he's got a better command of English than many Japanese writers on the subject.
The temple I tend to hang out with is actually Jodo Shinshu based (they've got a fun community and tend to be instigators of the local cultural and observance festivals like Obon). There's also a Nichiren temple in town but I've not spent much time there (location is inconvenient).
There's not really a well organized Zen temple in my area.. but then Zen adherents don't tend to be well-organized anyway
(herding cats)
I'll update this post with some books tonight that I've found helpful at least.
